Nina Agdal isn't a stranger to South Beach. A couple weeks ago she was spotted getting her tan on in a skimpy two-piece. Over the weekend, the 19-year-old Sports Illustrated rookie of the year attended the annual Model Beach Volleyball Tournament at Lummus Park in Miami Beach. All the top modeling agencies sent their hottest clients to participate, but it's hard to imagine anyone looking as hot as our new favorite, Nina, who showed up short shorts and cutoff shirt. Yeah, she's the real deal.
